Application filed August 22, 1917. Serial No. 187,524.

I '0 all whom may concern:

Be it known blliiiliili, Aneusr MATHIS, a citizen of the United gratesof America, and aresideut of Chicago, in the county of Cook, State oflllinois, have invented certain new and useful improvements inFire-Extinguishers, of which the following is a specification.

This invention relates to that type of portable lire-extinguishers inwhich the extinguishing solution of carbon-tetrachlorid or the like isforcibly ejected from a tank or reservoir by a pressure of air producedin said reservoir by an attached pump, and the present improvement hasfor its object:

To provide a structural formation and association of parts whereby theeduction nozzle or passage from the reservoir is kept in constantcommunication with the fluid regardless of the position of thereservoir, and without the necessity of valved mechaiisms, as thereservoir is manipulated in actual use to reach an incipientconfiagration.

in the accompanying draw1ng:.

Figure 1, is a central sectional elevation.

of a portable fire extinguisher to which th present invention isapplied. I

Fig. 2, is a bottom View of the same. Fig. 3, is an enlarged detailsection of the V flexible tube.

The same reference numerals indicate like parts in the several views.

Referring to the drawing, 1 designates a closed .tank or reservoir ofany usual and suitable form, and adapted to contain a fireextinguishingsolution of carbon tetrachlorid or the like.

Q'designates the usual-air pump arranged as a fixture at one end of thereservoir 1 and adapted for manual-actuation to create a pressure of airWithin said reservoir, as usual in the present type of ap aratus.

3 designates the outlet or e uction oriiice or nozzle of the apparatusclosed by a stop valve i of any suitable form, preferably of the slidingtype shown.

5 designates a flexible tube or conductor cornmunicathig one end withthe outlet nozzlefi aforesaid, and atits free end provided with a mobilesinker 7 hereinafter described in detail and by which the free end ofthe tube 5 is maintained in a submerged condition in the liquid. Thetube or conductor 5 is preferably formed by an outer tubular member ofclosely Woven fabric and an inner coiled spring or like re-inforce 6,;

affecting the required flexibility of said tube or conductor.

7 designates the sinker above referred to, and which is attached to andencircles the free end of the tube or conductor 5 aforesaid. In thepresent improvement said sinker comprises a weighted portion 8 arrangedat or near the free end of the tube or conductor 5, and a lighterportion 9 arranged remote from said tube end, as shown in Fig. l. Theaforesaid buoyant portion is preferably formed by an air filled semiglobular shell 10 of celluloid or the like.

The described arrangement of the sinker 7 is such that the free end ofthe tube or conductor 5 will be maintained at or near the lowest part ofthe fluid contents of the reservoir 1 regardless of the position inwhich the apparatus may be held by the user in actual use.

Having thus fully described my saidinversion what I claim as new anddesire to secure by Letters Patent, is

1. In a fire extinguisher, the combination of a reservoir having anoutlet-orifice, a flexlble tube communicat ngat one end with saidorifice and arran ed within said reservoir, and a mobile sinier attachedto the free end of said flexible tube and comprising a conicalweighted'portion located at or near the free endof the flexible tube anda lighter portion located remote from said who end, the sinker beingadapted to maintain said free end of the tube in an immersed conditionregardless of the posifree end of-seid flexible ture and compristion inwhich the reservoir is held, substaning a. weighted portion located ator near the 10 tially as set forth. free end of the flexible tube and abuoyant 2. In a fire extinguisher, the combination portion locatedremote from said tube end aofareservoir having an outlet orifice, aflexisubstantially as set forth,

ble tube communicating at one end with Signed at Chicago, Illinois, thisl5thday said orifice and arranged within said reserof August, 1917. vvoiz', and a mobilesinker attached to the AUGUST MATHIS.
